T&R F0357A High Voltage Potential Kit
The T&R F0357A High Voltage Potential Kit provides a practical way to confirm the presence of AC or DC voltage before maintenance or installation work. It detects voltage from 0.2kV up to 15kV and uses flashing neon indicators to give a clear visual response. The flash rate rises as the voltage level increases, helping the operator see the indication clearly during testing.
Compact construction makes the indicator suitable for confined areas such as switchgear panels, switchgear enclosures and busbar compartments. A proven resistor chain measurement method provides dependable voltage indication, while high immunity to electrical interference supports use around switchgear equipment. Clear safety limit marks, an operator hand guard and a viewing window further support practical field operation.
The T&R F0357A High Voltage Potential Kit also includes a battery-powered proving unit so the fully assembled indicator can be checked before and after use. The proving unit provides a nominal 300V DC output and includes an automatic battery check function. With indoor and outdoor use in dry conditions, AC and DC capability and an operating temperature range of -5°C to +50°C, the kit is designed for regular high-voltage testing work.
